Class

Her er en lille hurtig lektion i klasser, objekter og variable...

1) En klasse/objekt kender kun sine egne variable
2) En funktion i en klasse/objekt kan kun tilgå klassens/objektets definerede variable samt sine egne lokale variable (som ikke eksisterer efter funktionen er afsluttet)
3) For at en variabel skal kunne anvendes mellem 2 eller flere funktioner skal den,
- være erklæret som en klasse/objekt varibel ex "var $var1"
- gives med som argument til funktionen der skal anvende den, ex. "function print($var1){...}"
- erklæres som en global variabel i toppen af alle funktionerne, ex. "global $var1"

Sådanne her tilgås en klasse/objekt-variabel i en funktion

$this->var1 = 5; // $this refererer til det objekt man har fat i

Sådanne her tilgås en global-variabel i en funktion

global $var1;

//Nu kan vi anvende den globale udgave af $var1
$var1 = 5;

Så med mindre jeg ikke tager meget fejl har du glemt

1) at gemme $players & $maxclients i objekter, benyt $this->players, $this->maxclients til at hente/gemme værdierne i objektet, eller
2) variblene er globale og du har glemt at erklære den således, altså global $players, $maxclients[Redigeret d. 05/01-03 20:04:05 af Erik K. Aarslew-Jensen]

Hmm jeg bruge en anden lidt mindre tabel men samme problem med den! håber ikke at det gør noget!

	function DrawBotTable() {
	//Tager server infoen ud

	// udtagelse slut
					
	echo "mark: ";
	echo $this->hostname."=> ";
	echo " Map: ".$this->mapname;
	echo " Players: ".$this->numplayers."/12";
	}




    
    function players() {
    $i="0";
    while(list($key,$val) = each($this->player_info)) {
		$i=$i+1;
	}	
				    
	$this->numplayer=$i;
	global $this->numplayers;
	}

sådan ser det ud! men det virker ikke
hvad har jeg fjort galt?

Send mig hele koden for klassen så skal jeg nok se på det... det er et spørgsmål om hvordan du gemmer dine variable...


PS: global $this->var (Giver ikke mening at lave en objekt-variabel global)
